The cost to operate this foam separator is only a small amount of air (mount directly in the fish tank or sump), so water pumping is not required. A small ozone generator, used in combination with a foam separator, will further increase the removal efficiency.
1/4" I.D. air inlet requires .4 cfm @ 1.5 psi. We recommend one, operated continuously, for every 500 lbs of fish. Length is 20" and operates at a minimum water depth of 16". Ship weight 3 lbs. One-year warranty. Made in USA.
